4 0

Answer:

The answer is b = 8a

Step-by-step explanation:

As, 0 x 8 = 0

2 1/2 = 5/2, 5/2 x 8 = 20

5 x 8 = 40

7 1/2 = 15/2, 15/2 x 8 = 60

10 x 8 = 80

13 1/2 = 27/2, 27/2 x 8 = 108

So all variables "a" when multiplied by 8 will give us the value in "b"

So b = 8a

Machine A can complete a certain job in x hours. Machine B can complete the same job in y hours. If A and B work together at the
scZoUnD [109]

Answer:

\frac{y}{x+y}

Step-by-step explanation:

The required answer is the rate at  which Machine A  works when the two machines are combined.

Note: the rate of doing work is express as

rate=\frac{1}{time taken} \\

Hence we can conclude that Machine A working rate is

machine A=\frac{1}{x} \\ and machine B working rate is

machine B=\frac{1}{y} \\

When the two machine works together, the effective working rate is

\frac{1}{x}+\frac{1}{y}\\\frac{xy}{x+y}\\

The fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A

Hence the fraction of work done by A is expressed as

\frac{1}{x}*combine working rate

\frac{1}{x}*\frac{xy}{x+y}\\\frac{y}{x+y} \\

Hence the fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A is \frac{y}{x+y} \\
